DELTADUCT ® Code PAB103 The project is a spin-off from the discussion to deliberately flood "inter-river" areas. We abolish all solid infrastructure within the delta, to reestablish the wildlife zone. Main infrastructural lines remain, but will be rebuilt elevated. This new hybrid inbetween the bridge, house, harbour, and the "dam" is called DELTADUCT. The whole project is a spin-off from the discussion to deliberately flood some "inter-river" areas, instead of "artificial" and increasing maintainance of the dykes. The idea of returning to the "natural" state and de-organisation is appealing, but has to be appplied consequently. Therefore we propose to make a FULLY WILDLIFE DELTA. Within it we introduce two zones of the "riet-heliofiten" filters, that would purify the water before getting into the North Sea. First filter zone at the beginning of the delta ensures the water cleansing for the wildlife species. This process develops over a period of time. The existing man-made landscape articulation gradually loses it's asphalt roads to swampy areas , fish farms, wild strawberry fields, canoe cabins and bird-watchers paradise. Overlapping of the old landscape and the landscape in making, makes this a specific place to begin a journey. The journey starts when you step out of the car at the beach slope, walk over the Deltaduct 2 and slip into the new wildlife. Any type of habitation within the Delta demands the infrastructure to get to it. We propose the abolition of all solid infrastructure within the delta realm, to reestablish the wildlife zone. Only the main infrastructural lines connecting Randstad to the rest of Europe will remain, but will be rebuilt elevated from the wet natural grounds below. THIS HYBRID INBETWEEN THE BRIDGE, HOUSE, HARBOUR, CIVIL WORKS, TRAIN STATION AND THE "DAM" IS CALLED DELTADUCT ® All future habitations are to be placed within the D-ducts. There are three main types of DELTADUCTS depending on their level of interactivity and their position within the delta. Being located at the traffic interface inbetween the Randstad and major western europen cities, together with the condition of living in the wildlife makes this a perfect location for housing. DELTADUCT 1 / 200 km/h(sea-business) is placed near the sea. Floating above bigger islands and the "sweet-and-salty" waters. It acts as the traffic sign for the big boats denouncing the water levels (like the lighthouse). It has no direct physical contact with the delta. D-duct 1 is interacting with the delta only visually. Houses parasite on the view and the immediate connection to work-places. That is a perfect position to have a business meeting or a conference. It's quick. It is made from kevlar: a light strong technically advanced material. From the Dduct itself there is only alternating visual connection to the amazing big views.It becomes also the shiny finish line for the sail competitions. DELTADUCT 2 / 40 km/h (swamp-nature) is placed in the swampy wildlife wetlands. D-duct 2 is highly interactive, sometimes merging its slopes with the delta itself. The exact form of infrastructure merges with the beach at it's slopes and sometimes, it's flooded. This slow spine goes up and down directly aproaching the water level, where your boat lies. That is also where most nature freaks set-off for drifting into the delta. Houses there get a direct acess to the wildlife, while being connected to efficient traffic routes.They sometimes lay in the water and sometimes just above it. Fish farming is a popular activity there. It's also famous for it's fish restaurants.The speed is slow. It's made from concrete, sand, wood and riet . Some parts fall off, and the other emerge. It's like an animal. DELTADUCT 3/ 100 km/h (wet/dry- recreation) is placed at the beginning of the delta. The differences between high and low (dry ) condition are most extreme. That is where recreational sailors meet in water bars, and where you swim in a pool above the wildlife delta. Disco opens at night. In summer there are also strawberries available. Houses form clusters under and above the driving route. Interaction with the delta is always through an intermediate space both being connected up and down, like the transferiums from car/train to the Delta Ferry/ recreational boat. The speed is moderate. Material is steel and concrete, partly prefab. You do not have to pay toll on none of DELTADUCTS ®.
